However, Sony Mobile’s head of Xperia marketing Calum MacDougall told Reuters that Xperia Z sales have “got off to a good start.”

In Germany, the Xperia Z sold out in two hours, while in France the company sold more Xperia Z units in a day via its online store than the number of total mobile devices sold in 12 weeks through the same channel.

In Japan, the Xperia Z sold over 150,000 units in the first week since launch, “taking a 24 percent market share straight away.” Sony appears ready to offer sales numbers only for Japan, Sony’s home turf, where the handset went first on sale.

Then again, this isn’t the first time we hear that the Xperia Z is popular in Japan and Europe. But what about the U.S.? The Xperia Z is not available in the America, a market without which Sony can’t really complete its mobile dreams.

However, Sony is yet to prove it can sell a significant number of flagship devices, and it will have quite a difficult road ahead this year, as the Xperia Z will face some stiff competition from the HTC One, Samsung Galaxy S4 and Google X Phone, to name just a few of the most important Android handsets of the first half of the year.
